MACHINE FOR FLANGING UPPERS OF BOOTS OR SHOES.

SPECIFICATION forming` part' of Letters Patent N0. 548,184, dated. October 22, 1895.

Application iiled February 23, 1895. Serial No. 539,483. (No model.)

.fb all whom t may concern:

Be it known that I, CHRISTIAN CHAsREL EISENBERG, of Berlin, Germany, have invented an Improvement vin Machines for Flanging the Uppers of Boots or Shoes, of which the following is a specification.

My improvement consists in a machine for forming a Ilange or rim around the uppers of boots and shoes of all kinds.

The object of my invention is to so construct a machine that a ange or rim may be readily and conveniently formed all around the lower edge of the upper of a boot or shoe; and it consists in certain details of construction which will be hereinafter fully described.

Referring to the drawings, forming a part of this specification, and on which like letters and numerals indicate corresponding parts, Figure lis a side elevation of the machine. Fig. 2 is a top plan view thereof. Fig. 3 is a view similar to Fig. 1 with the working mechanism in a different position. Fig. 4 is a View corresponding with Fig. 2 with the working parts in a different position. Fig. 5 is a view partly in section, taken on the line :10,Fig. 1. Figs. 6 and 7 are details to be hereinafter referred to.

O is a column or base on which is mounted the head-plate h, to which the vertical supports c c are bolted or otherwise properly secured. (See Fig. 7.) On top of the supports c c is secured a plate d., having the general outline of the sole of a boot or shoe. This plate d is provided with a tenon 1, which engages a hole or opening 2 in one of the standards c, and thussecures the plate d in position. Two arms or brackets 3 4 project outwardly at each side of the column or base c and support the right and left screw-threaded rod or spindle 5. At each end of this rod or spindle 5 is a hand-wheel h for operating the same. j

rlwo nuts c' e', one at each side ofthe machine, are provided, and each of the nuts carries a plate 10, for a purpose which will be presently explained. The nuts t' t' are tapped to engage with and be operated by the screw rod or spindle 5, and they are arranged to slide in ways in the top of the arms-or brackets 3 4. (See Figs. 1 and 5.) To the plates 10 are secured pressureplates 11 11, and the inner edges of these plates 11 are shaped to conform to the shape of the shoe. The plates 11 are connected to the plates 10 and made so as to be readily detached from said plates by means of a ball-and-socket connection on the plate 10 and nuts, and are held in place by means of slides 12, which are secured to the nuts so as to prevent the disengagement of the ball-and-socket connections unless it is desired to remove the plates.

The plate b is provided at suitable points with a series of clamp fingers or tweezers g, which extend upwardly therefrom, and the jaws of these clamps may be opened or closed by means of the thumb-screws 7, (see Fig. 6,) while the fingers or tweezers may be adjusted up or down and held in place by the wing or thumb-screws 6 on the lower ends of the clamp-rods, which preferably pass through holes in the plate b and have the thumbscrews on the under side thereof.

The plate d, which supports the last, has preferably a circumferential groove in its edge to receive the edges of the plate 11.

A curved plate 14 the shape of the heel of the shoe is pivoted to one of the plates 11. It is provided with a handle for operating it and carries a toothed ratchet which engages with a pawl or pin on the other plate. A similar plate 15, with its handle, pawl, and ratchet, is provided at the toe of the shoe or last.

Screw-rods 18 19, operated by thumb-nuts, may be used to bear against the plates 14 15, and springs may also be'used to hold the ratchets and pawlsin engagement.

Instead of the mechanism just described for forming the fiange or rim at the heel and toe, I sometimes duplicate the mechanism used for forming the side flangese-that is to say, another screw rod or spindle and two arms at right angles to the rod 5 and arms 3 and 4 would be used with the sliding nuts, plates, and other mechanism, the only change necessary being to form the plates the shape of the heel and toe.

The operation of the machine is as follows, viz: When the pressure-plates '11 have been brought into the position shown in Fig. 3 by turning the `hand-wheels, the last is secured roo to the plate d, the upper mounted thereon and drawn down over the edge of the plate and clamped by the cheeks ofthe jaws o r tweezers. When the edges of the upper have been clamped at enough places, the nuts 6 are turned until the upper is stretched tight on the last. When this has been done, the slides z' t' are brought closer together by revolving the screw rod or spindle and engaging with the upper at a point between the bottom of the last and the plate d, and this operation forms the flange or rim. The rim d practically forms a groove with the plate and as the slides 11 11 are advanced hold the leather securely. The flange at the heel and toe is formed by means of the curved plates 14 15, operated by the handles in a manner that will be readily apparent. After these plates have been forced against the upper they may be still further advanced and the pressure thereby increased by operating the screws 18 19. In order that the shape thus given the upper may be retained, the upper, with the last and the parts 1l, 14, and 15 are taken out of the machine and placed in a drying room or space. After the upper is completely dry and the Iiange or rimis permanent the screws connecting the plate and the last are removed and the latter is allowed to remain in the shoe untilitistinished. Iamthusenabled toavoid changing the last so often as in the usual manner and to preserve the shape of the shoe throughout the entire process of manufacture and not distort or disfigure the same, as in the common methods. Another advantage of the machine is that the whole operation is performed with the last right side up, so that the work being done is always in full view of the operator, which is not the case when the last is inverted, as in the old way, or, in other words, with the sole up.

Minor changes may be made in the details of construction without departing from the spirit or sacrificing any of the advantages of the invention and still be within the scope thereof.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a machine for tlanging the uppers of boots and shoes, a supporting plate for the last, clamps or tweezers for drawing down the edge of the upper, sliding plates for hanging the sides of the upper and mechanism for operating the same, separate plates for flanging the heel and toe, the last and Hanging plates all being removable from the machine, substantially as described.

2. In a machine for fianging the uppers of boots and shoes, a supporting plate for the last, means for clamping the plate to the latter, a plate beneath the last provided with a series of clamps or tweezers for drawing down the upper, sliding plates for Hanging the sides of the upper, a right and left screw for operating them, and separate plates for the heel and toe, and means for operating them, substantially as described.

3. In a machine for Hanging the uppers of boots and shoes, a suitable support or stand, a right and left screw rod or spindle mounted thereon, and means for revolving it, tapped nuts carried by said rod, removable side lian ging plates carried by the nuts, separate heel and toe langing plates, means for operating them and locking them in closed position, and a supporting plate for the last, substantially as described.

4. In a machine for Hanging the uppers of boots and shoes, a supporting plate for the last and means for clamping the latter thereto, side Hanging plates and separate heel and toe Hanging plates, all of which are removable from the machine, substantially as described.

5. In a machine for Hanging the uppers of boots and shoes, a suitable support or stand, a right and left screw rod or spindle mounted thereon, moans for operating it, tapped nuts carried by said rod, side iianging plates carried by the nuts, separate heel and toe Hanging plates, levers or handles for operating them, screw rods or nuts for giving additional pressure, and a last supporting plate and last, substantially as described. u

In witness whereof I have hereunto set my hand in presence of two witnesses.
